#ZBRUSH SYMMETRY HOW TO#

The algorithm is slow for really high poly meshes.It isn’t perfect it can struggle with complex shapes.Lots of control and different tools to help.Can create great topology for some types of models.

In the below example I have run all 3 algortyhtms so you can see their subtle differences. The third is holding alt when you press the ZRemesher button. The second clicking the Legacy 2018 button then the Zremesher Button. The first is simply clicking the Zremesher button. As I mentioned there are 3 algorithms to use when Zremesheing the first 2 are obvious but the third is secret!! In this example I am going to set my target poly count to 0.5. The Zremesher can be access through the geometry menu on the right. Lets once again start with our 40k poly ring. In most part you could use Zremesher to create your final topology however this is very much dependent or what you are retopologizing. You may be unaware that Zremesher actually has 3 different algorithms which it gives you access to. It allows such things as freezing borders, identifying edges and using poly paint to dictate poly density to name a few. There are various ways to use this tool and its worth trying them out. Zremesher is Zbrushes best attempt at an automated retopology tool.

Use this tool to eliminate hidden topology and merge any points that arn’t connected.

This function is best used for creating more topology or evening out the topology for better sculpting.

If using to produce final topology play around with the different resolutions until you get the desired result.

Algorithm is not optimal to be used as final topology.

#ZBRUSH SYMMETRY HOW TO#

No flexibility as to how to set out topology.It merges any toplogy that is not connected eliminating unwanted polys.In this case it has help its shape pretty well and been reduced to 1.5k polys however you are not always this lucky. If all goes well your model should reduced in polys as per the below. If you get no effect you just need to make a small change to your model so turn smooth intensity down for instance smooth and try again. You will notice nothing has happened to your mesh yet, this is because you need not now go into the drawing panel not on you mesh but to the side hold ctrl and drag (Who would have guessed right). Once there it is as simple as selecting you desired resolution as per below. In the menu on the right hand side select Geometry and navigate to the Dynamesh section. Example of How to Useįor this example we will use a ring that come stock standard with Zbrush that has 40k polys. Its biggest draw back is you have very little control how it retopologizes, however its uses are fantastic for the sculpting process. Dynameshĭynamesh is a useful retopology tool and it is 100% automatic, however it is in most cases not ideal for a final model. In short retopologizing is an extremely important part of the 3d modelling pipeline and ensuring this is done correctly can greatly improve your model and your workflow. Good topology can help with the UV process allowing for seams to be placed in ideal places and UV’s to be utilised to thier fullest to assist in the texturing process. If you are curious please check out my article on this here. Retopology may not just be about reducing the poly count, by refining the wire frame it can assist with how your model deforms during animation. Real time rendering for example in game engines cannot handle large poly counts, so it is essential to get the poly count as low as possible. While this is manageable in Zbrush other 3d programs will not be able to handle the increased load this puts on the system to be able to render this many polys. In the process of sculpting and creating a 3d models particularly in Zbrush your poly count can easily blow out into the millions. Retopology is the process of refining the wire frame of your 3d model so it is more manageable to use in a 3d modelling pipeline

This can slow or stunt your workflow having to regularly change between programs. These tools are not necessarily obvious in Zbrush so they are often overlooked in preference of using other programs for retopology. Gaining an understanding of these and their limitations can help you make informed decisions that can greatly speed up your workflow. They range from completely automated tools to completely manual. Zbrush has various retopology tools you can utilise.
